The invention provides a communication system used in a coal mine for drawing a mine car from the front and the back by using double locomotives. The communication system comprises a first transceiver, a second transceiver, a first controller, a second controller, and a plurality of repeaters. The first transceiver communicates with the second transceiver, such that a controlling system with a communicational relationship is formed between the first controller and the second controller. Therefore, synchronous operations of the two locomotives can be realized under controlling. The plurality of repeaters are arranged at curved channels of drifts in the coal mine. The repeaters are used for repeating signals transmitted by the first transceiver to the second transceiver, or repeating signals transmitted by the second transceiver to the first transceiver. Therefore, communication can be continuously ensured between a front locomotive and a back locomotive. Thus, the two locomotives can operate in coordination wi
